Hello All, I'm currently upgrading my homebrew equipment, in order to have more control over the whole brewing process. At this point, I use store bought malt extract (sugars extracted from grains) to create the fermentable liquid that becomes beer, but I would like to start brewing with all grain and perform the sugar extraction process on my own. That having been said, what I plan to construct is what is referred to as a lauter tun. It will be a 10 gallon insulate container in which near boiling water is mixed with grain, and the temperature of the water, grain sludge must be temperature controlled. Current options I have to control the temperature are an electric heated rod or a recirculation system with a heat exchange. I decided, after some research, to employ steam heat. Steam heat has advantages over the other options because heat is transferred more quickly and it is cheaper. For the container I plan to use a Gott 10 gallon cooler. I plan to use a PID temperature controller with a temperature probe to monitor the temperature of the liquid and control the functions I need to control. To employ steam heat I plan to purchase an electric pressure cooker and fasten plumbing to it which will run through a solenoid gas valve to the lauter tun. The steam will exit through nozzles into the hot liquid. In order to distribute the heat evenly, a motorized stirrer will mix the concoction. The problem is I need to have the valve turn off when the liquid has reached its target temperature, the pressure cooker must turn down (but not off), and the motorized stirrer off. When the liquid is too cool, I must have the PID controller turn on the valve so that it opens, turn on the pressure cooker, and turn on the motorized stirrer. I 'do not really understand at all how these components will connect and I do not wish to destroy them or myself when connecting them.

Could someone tell me what components I will need for this and how to connect them? I will send you a 6-pack of the next beer I brew and I will be extremely grateful. They are outstanding brews by the way!
